There aren't many options in the DC metro area for plumbers who are open for business 24x7. Benjamin Franklin is one of them. Between reviews on Angie's List and the fact the previous occupants of our house used Benjamin Franklin, we gave them a call. Within a few hours the plumber arrived, diagnosed the problem, and provided a cost estimate of the work. The plumber was courteous and professional and completed the work in a timely manner. I would definitely use them again!
